Industry Context

The global electricity demand outlook shows a 4% CAGR from 2025-2030, while global energy storage annual additions are projected to grow at a 12% CAGR, indicating energy storage is growing 3-4 times faster than power demand. Powering AI/Data Centers is highlighted as the fastest-growing energy storage segment at a 28% CAGR. Energy Vault is strategically positioning itself as an integrated storage IPP to capitalize on this imperative for energy storage, particularly in supporting the massive AI infrastructure build-out.

Comparison to Industry Standards

• Energy Vault aims to build the only listed integrated energy storage IPP, offering a compelling mix of high growth and low volatility.
• The company compares its target EV/EBITDA multiples to IPP/YieldCo comps, which typically range from 15x-18x.
• It differentiates itself from 'Clean Energy' companies (e.g., AMRC, ARRY, BE, FSLR, NXT, RUN, SEDG) which have moderate revenue growth and volatility.
• It also differentiates from 'Renewable IPPs' (e.g., CEG, NRG, TLN, VST) which exhibit high revenue growth and volatility.
• Energy Vault positions itself closer to 'Asset Owners / YieldCos' (e.g., BEP, CWEN, HASI, ORA) in terms of low revenue volatility, but with higher growth potential due to its integrated model and market focus.

Stakeholder Impact

• Shareholders: Expected to benefit from increased shareholder value through a non-dilutive financing structure, significant recurring EBITDA growth, and potential rerating of the company's valuation.
• Customers: Enhanced ability to deliver critical energy infrastructure and advanced energy storage solutions, particularly for the rapidly growing AI/Data Center segment.
• Employees: Potential for growth and expansion as the company scales its operations and project pipeline.
• Suppliers: Continued engagement and optimization of the supply chain, including strategic partnerships and efforts to mitigate tariff and FEOC compliance risks.
• Creditors/Lenders: Opportunities for project debt financing as Asset Vault continues to raise capital for its projects.

Next Steps

• Release of Q3 Results on November 10, 2025.
• Ribbon Cutting for the Energy Vault Solution Excellence Center in Snyder, TX, on November 21, 2025.
• Expect to draw nearly $200 million from the OIC preferred equity facility over the next six months.
• Commence work on two late-stage projects in the US and Australia.
• Advance additional pipeline project development.
• Sosa project: Q4 2025 site mobilization for safe harbor FEOC, project financing underway, target NTP Q4 2025, target COD Q1 2027.
• Stoney Creek project: Target NTP Q1 2026, target COD Q4 2027.
• Safe Harboring 750MW+ of Asset Vault projects through year-end 2025 to lock in ITC qualification.
• Procurement of Main Power Transformers by year-end 2025 for other near-term US projects (2027+ COD) to safe harbor an additional 600MW.

Recommendation

The filing outlines a highly compelling strategic pivot with the Asset Vault platform, backed by a substantial $300 million non-dilutive preferred equity investment from OIC. This provides a clear, funded path to significant recurring EBITDA generation ($100-150M annually by 2029) and positions Energy Vault at the intersection of two high-growth sectors: energy storage and AI/data center infrastructure. The company's proven execution, robust project pipeline, and strong financial guidance for 2025, combined with a strategy to achieve higher valuation multiples comparable to IPPs/YieldCos, make this a strong buy for long-term investors seeking exposure to critical energy infrastructure and AI enablement.
